HP 316095-B21 Installation Manual page 18

• Microprocessor and functional logic for the control processor (CTP) (and firmware is loaded
from FLASH memory).
• Ethernet LAN interface, causing the connection to the HAFM appliance to drop momentarily
until the connection automatically recovers.
• Ports, causing all Fibre Channel connections to drop momentarily until the connections
automatically recover.
An IML should be performed only if a CTP failure is indicated. Do not perform an IML on the
Edge Switch unless directed to do so by a procedural step in this manual or by the next level of
support. As a precaution, the IML button is flush mounted to protect against accidental
activation.
• SFP fiber-optic connectors
A single-mode or multimode fiber-optic cable attaches to a port through an SFP transceiver. The
SFP transciever provides a duplex LC interface and can be detached from the Edge Switch port
for easy replacement. Two fiber-optic transceiver types are available:
• Short-wave laser—Short-wave laser SFP transceivers provide short-distance connections (2 to
500 meters) through 50-micron or 62.5-micron multimode fiber.
• Long-wave laser—Long-wave laser SFP transceivers provide long-distance connections (up to
10 kilometers) through 9-micron single-mode fiber.
• Extended long-wave laser—Extended long-wave laser SFP transceivers provide long-distance
connections (up to 35 kilometers) through 9-micron single-mode fiber.
• Port LEDs
Amber and green LEDs adjacent to each port indicate operational status:
• Amber LED illuminates to indicate a port failure.
• Amber LED flashes to indicate a port is running online diagnostics or beaconing is set and
the port is not communicating (no SFP tranciever installed, no cable attached, loss of light,
port blocked, or link recovery in process).
• Green LED illuminates (or blinks) if there is active traffic.
• Both LEDs extinguish to indicate a port is operational but not communicating (no SFP
tranciever installed, no cable attached, loss of light, port blocked, or link recovery in
process).
